Abstract (en)
[origin: EP4020966A1] Embodiments of this application provide a callback stream processing method and a device, and relate to the field of electronic technologies. In a callback stream scenario, an electronic device may set a preview stream and a callback stream in parallel. After an application sets a callback function, the electronic device may directly return, by using the callback function, callback stream data to the application for processing. This can shorten a time consumed for creating a preview stream and a callback stream, shorten a time consumed for obtaining callback stream data, and shorten a user waiting time. A specific solution is as follows: After detecting a first operation that a user uses a first function of a first application, the electronic device starts a camera application; displays a first interface corresponding to the first function; creates a preview stream and a first callback stream in parallel; obtains first data, where the first data is callback stream data corresponding to the first callback stream; sets a callback function; and provides, by using the callback function, the first data for the first application for processing. The embodiments of this application are used to process a callback stream.
